11.1.3.1.2. Electrical Circuitry
The sequence of operations used for the Saddle Stitch is controlled by the Saddle Stitch Controller PCB.
The Saddle Stitch Controller PCB has a microprocessor. This microprocessor is used to control the
sequence of operations and to handle serial communications with the Finisher Controller PCB, driving
solenoids and motors in response to the various commands from the Finisher Controller PCB.
The Saddle Stitch Controller PCB is also used to communicate the state of various sensors and switches to
the Finisher Controller PCB in serial.
The functions of the major ICs mounted on the Saddle Stitch Controller PCB are as follows:
•Q1
Controls the sequence of operations.
•Q2
Contains sequence programs.
•Q3
Controls the sequence of operations.
•Q4
Handles IPC communications.
